"I got several estimates from several providers. The pricing seemed just ok with those other providers but something seemed off. Good Life came in and made sure that I was getting the correct amount of insulation (where the other service providers had under estimated) and helped me to get into a loan through the utility company for the cost of the insulation. Good life is a qualifying contractor for this and it saved me a lot of out of pocket expense. They came in and did what they had to do. They were professional and made sure the work was done well."

"My experience with everyone was excellent. It started with an energy assessment followed up with spray foam insulation throughout my home. Good customer service and follow-up. All was explained thoroughly throughout the process and they welcomed my questions. I highly recommend this service."

"The crew worked quickly and efficiently to replace and upgrade the fiberglass batts in our basement and crawl space. I’m pleased with the outcome. (I put in even more wire supports afterwards — to secure the insulation between the joists — but that’s just my OCD.) It was a relatively small job for this company and I thought the cost was fair."

"Very professional company. From the initial contact, inspection and quote by Brian, to prompt scheduling follow-up by Jessen and arrival of the team, everything went seamlessly. Would definitely recommend this company. Jabari and Anthony did a great job insulating the rim joists, adding wall and pipe insulation under the sink on an outside wall and caulking a leaky window - no more breezes. Definitely feel a difference in the house now. The added attic hatch cover makes the heat stay below, where it belongs. Really appreciated the use of PPE when they were working with mineral wool. Very satisfied customer here."

"Ecofoam insulated my attic with closed-cell spray foam and the results came out great. The space feels completely sealed and much more comfortable already. Sevi and the team were very professional, easy to work with, and kept me updated throughout the whole process. I would highly recommend EcoFoam for anyone looking for quality insulation work."

"I liked that the first questions we were asked was "Have you had a home energy audit done? Did you know you can get a rebate on your insulation project?" Before even knowing the scope of our project, they were looking to help make it more affordable for us."

Insulation FAQs, answered by experts

Most homeowners installing blown-in insulation as a one-off DIY project should simply rent a blower. They tend to be very heavy, and contractor-grade machines can cost $13,000 to $16,000.

It depends on your needs and preferences, though many homeowners think it is worth it. Not only is blown-in insulation easy to install, but it is highly efficient with thermal regulation. Most types are mold-resistant, flame-resistant, insect-resistant, and, most importantly, completely safe.

Fiberglass is considered a favorite garage insulation choice due to its combination of affordability, ease of installation, and overall effectiveness. Fiberglass provides good thermal resistance, helping regulate garage temperatures and minimize heat transfer. Additionally, fiberglass is moisture-resistant, reducing the risk of mold or mildew formation.

The most affordable way to insulate behind unfinished walls is to install fiberglass batts or rolls. These total around $0.75 per linear foot, with the width matching the gaps between standard studs perfectly. However, it’s important to consider the R-value of your insulation and the climate in your area, as fiberglass insulation isn’t the best in terms of preventing heat transfer. Plus, the most affordable option may cost more on electricity bills over time. The most affordable way to insulate behind finished walls is to leave them up and use blown-in insulation to avoid drywall replacement.

These two types of foams are similar chemically, but they are applied in a much different way and each has its own pros and cons. Spray foam can only be used if the area where you will be installing the installation is wide open and easy to access. Injection foam should be used where it's cost-prohibitive to remove the walls that are placed over the insulation. Spray foam is a much less expensive process and requires less expertise.
